ABSTRACT:
A SigSauer pistol is modified to hold on the inside of its plastic handle grip an antenna assembly and spring contacts connected conductively to the antenna assembly. A modified magazine casing in the handle of the pistol has a chamber below a false bottom for receiving batteries and a printed circuit board carrying a radio transmitter and microphone. Electrical contacts on the outside of the magazine casing engage the spring contacts on the inside of the handle grip when the magazine casing is slidably inserted into the usual metal handle body on the pistol. Corresponding contacts on the inside of the magazine casing engage contacts on the printed circuit board that are connected electrically to the transmitter. Downwardly-facing battery switch contacts in the chamber are connected electrically to the transmitter and are positioned to engage respective terminals of two series-connected batteries.
